Problems achieving glow around lights
You´re on the right track. After you do what you show on your picture, you need to go to the COMPOSITOR, and add a GLOW node, to help you boost the look you´re going for.
Also if you want "in scene" glows, you need to create a cube, set it to wireframe visual override, use the cube with a VOLUME material, set density to 0.02 and and there will be a soft "mist" on your scene which now the light can bounce and absorbe from the lights.
When you take your render into the compositor, you can adjust brightness and contrast to intensify the look of the lights. 
You can also set a general volume pass for the world.
